Description

Construction method of building structure

The present invention relates to a method of constructing a building structure.

In general, decorative panels are often finished in the form of curtain walls to decorate the exterior walls of buildings. Recently, as a decorative panel, granite or marble is processed and used in the shape of a square flat plate.

There are two methods for installing such decorative panels: a wet method and a dry method. Among them, the wet method is a method in which cement mortar is applied to the outer wall of the building and the back of the panel, respectively, and directly installed on the outer wall of the panel. Due to the fact that curing takes a lot of time and safety accidents occur due to the fact that the panel falls from the outer wall of the building, the dry method is being used a lot in recent years.

In the dry construction method, a support frame for constructing a panel was installed on an exterior wall of a building, and the support frame and the panel were directly fixed with bolts to be installed.

However, when the decorative panel and the support frame are fixed to the outer wall of the building by bolting, the bolts may protrude to the outside and damage the aesthetics. .

However, the plate structure made of stone or metal is difficult to handle because of its heavy load, and since it must be constructed from the outside of the building where the wall has been completed, a high-rise building entails a long period of high-altitude work.

Furthermore, the fixture for fixing the plate structure to the wall of the building represents a simple structure in which the plate structure is fixed later with bolts and nuts after being pre-fixed to the anchor bolts on the wall, the wall and the plate structure Since the fastening of bolts and nuts is carried out in a narrow space between them, the work is difficult, and there is a problem that partial repair or replacement is impossible unless the entire outer wall is removed after construction is completed.

In particular, recently, in order to simplify construction, research has been conducted on a method of forming exterior panels on the exterior wall of a building using a large block unit formed by mounting a plurality of exterior panels on the frame unit in advance, rather than forming one on the exterior wall of the building. is in progress

Such a large block unit may be formed by combining a plurality of building panels to a frame, such as a base metal. However, in the conventional large block unit, due to the weight of each large block unit being between 1.5 and 5 tons, the frame of the large block unit is bent during the process of standing up for construction on the outer wall of the building. Due to this, it was difficult to construct a large block unit in a building.

For example, in the fixing step, the first frame unit coupled to the first side end of the first large block unit and the second frame unit coupled to the second side end of the second large block unit are installed facing each other and spaced apart can be

Here, the first side end of the exterior panel for construction included in the first large block unit protrudes more than the first frame unit coupled to the first side end of the first large block unit, included in the second large block unit It may be overlapped with the second side end of the exterior panel for construction.

As another example, in the fixing step, the frame unit coupled to at least one of the first side end and the second side end of the first large block unit is to be overlapped with the exterior panel for construction included in the second large block unit. can

Here, the frame unit coupled to at least one of the first side end and the second side end of the first large block unit is at least one of the first side end and the second side end of the exterior panel for construction included in the first large block unit. It may be positioned to protrude more than one side end.

The construction method of the building structure according to an example of the present invention can occur in the process of erecting the large block unit by rotating the large block unit to stand in a state in which the large block unit is levitated in the air when the large block unit is constructed in a building. By minimizing the bending of the large block unit, it is possible to minimize possible installation errors.

When the outer wall of the building 10 is constructed using such large block units MB1 to MB4, the construction period of the building 10 can be greatly shortened.

However, such large block units (MB1 ~ MB4) due to excessive weight, the frame of the large block unit (MB1 ~ MB4) in the process of vertically standing in order to construct the outer wall of the building due to problems such as bending , there were difficulties in constructing the building.

Hereinafter, when constructing the outer wall of the building 10 using such a large block unit, a construction method of a building structure capable of minimizing the bending problem of the large block unit will be described.

Figure 2 is a view for explaining a construction method of a building structure according to an example of the present invention, Figure 3 is a diagram for explaining in detail the frame arrangement step (S100) and the large block unit formation step (S200) of Figure 2 , Figures 4 and 5 are diagrams for explaining an example of the frame unit 110 formed in the frame arrangement step (S100) of Figure 2, Figures 6a to 6d are the standing step (S300) of Figure 2 in detail FIG. 7 is a diagram for explaining the fixing step S400 of FIG. 2 in more detail.

As shown in Figure 2, the construction method of the building structure according to an example of the present invention includes a frame arrangement step (S100), a large block unit formation step (S200), a standing step (S300) and a fixing step (S400). can

In the frame arrangement step S100 , as shown in FIG. 3 , the plurality of frames 110 may be disposed on the pedestal 20 in a horizontal direction on the ground. Here, the plurality of frames 110 may be formed to include an iron material, and, as shown in FIG. 3 , may be disposed on the pedestal 20 disposed in the horizontal direction parallel to the ground in the frame arrangement step S100, and the pedestal It may be assembled or combined on the 20 to form a single frame unit 110 .

As such, the plurality of frames 110 may be assembled or combined on the pedestal 20 to form a single frame unit 110 . Here, the plurality of frame units 110 are, as shown in FIGS. 4 and 5 (a), a first frame 110P1 extending in a first direction (x) and a first frame extending in a second direction (y). It may include a second frame 110P2, and the first frame 110P1 and the second frame 110P2 are assembled and coupled to each other as shown in FIGS. 4 and 5 (b), and thus one frame. It may be formed as a unit (110a, 110b).

Here, the first direction x of the frame units 110a and 110b may be the width direction of the frame units 110a and 110b, and the second direction y may be the length direction of the frame units 110a and 110b. have. That is, the length of the frame units 110a and 110b in the second direction (y) may be formed to be longer than the length of the frame units 110a and 110b in the first direction (x), and the frame units 110a and 110b may have a second direction (y) length. A large block unit can be constructed in the direction (y) parallel to the vertical direction of the building.

As such, in the frame arrangement step (S100) of the present invention, the case where a plurality of frames 110 are assembled and combined with each other on the pedestal 20 to form one frame unit 110 has been described as an example, but the present invention The present invention is not necessarily limited thereto, and a case in which one frame unit 110 already assembled and coupled is disposed on the pedestal 20 may be included.

When such a frame unit 110 is disposed on the pedestal 20, a large block unit forming step (S200) of coupling the exterior panel 100 for construction on the frame unit 110 may be performed.

In this large block unit forming step (S200), as shown in FIG. 3 , the rear surface of the plurality of exterior panels for construction is coupled to the frame unit 110 arranged in parallel with the ground to form a large block unit. can

In this large block unit forming step (S200), both ends of the frame unit 110 in the width direction are formed to overlap at least one end of both ends of each exterior panel 100 for construction forming the large block unit, or both ends It may be formed to be spaced apart from the end of at least one of the stages. Such a structure will be described in detail below with reference to FIG. 9 .

In this way, in the large block unit forming step (S200) of the present invention, in a state in which the frame unit 110 is arranged in parallel with the ground, a plurality of exterior panels 100 for construction are laid on the frame unit 110, and then the coupling member Since a plurality of exterior panels for construction 100 are combined on the frame unit 110 using can be more precisely coupled to the frame unit 110 , thereby minimizing deformation of the frame unit 110 .

In the standing step (S300), the large block unit MB may stand in a vertical direction intersecting the ground in a levitated state. That is, in the standing step (S300), the large block unit MB may be rotated to stand upright so that the inclination angle formed with the ground is greater than or equal to a predetermined angle in a state in which it is levitated in the air.

In the general step of standing of the large block unit, in a state in which one end of the large block unit MB is supported against the ground, the other end is lifted to stand the large block unit MB.

However, when the large block unit is erected in this way, one end of the large block unit (MB) is in contact with the ground while lifting the other, the moment the other side of the large block unit (MB) falls from the ground, An excessively large weight of the plurality of exterior panels 100 for construction may be momentarily concentrated on one end of the large block unit MB in contact with the ground.

In this case, the portion of the frame unit 110 adjacent to the ground exceeds the allowable weight limit that can be endured in the transverse direction intersecting the longitudinal direction of the frame unit 110, so that a portion of the frame unit 110 is a plurality of architectural exteriors. The panel 100 may be bent because it cannot withstand the weight of the panel 100 . Accordingly, a phenomenon in which the large block unit MB is bent may occur.

However, in the standing step (S300) of the present invention, unlike the standing step (S300) of the general large block unit (MB), the large block unit (MB) stands in a suspended state in the air, a plurality of exterior panels for construction (100) Minimizes the phenomenon in which the weight of the frame unit 110 is concentrated on one part, and distributes the weight of the plurality of exterior panels 100 to various parts of the frame unit 110, so that a plurality of exterior panels for construction ( The bending phenomenon of the frame unit 110 due to the weight of 100 can be minimized.

To this end, the standing step (S300) may include a lifting step (S310) and a rotating step (S320).

In the lifting step (S310), as shown in Fig. 6a, the chains 51a to 51d of at least one hoist 50a to 50d provided in the lifting bar 30 connected to the crane are large block units (MB) of In the state connected to the corner, the large block unit (MB) can be levitated in the air.

In order to perform the lifting step (S310) in this way, the crane and the lifting bar 30 may be used. The floating bar 30 extends long in one direction, may be connected to the hook 40 of the crane through the hook wire 41, and may be spaced apart from the upper part of the large block unit MB. At this time, it may be arranged in parallel with the front surface direction of the large block unit MB of the buoyancy bar 30 .

At least one hoist (50a ~ 50d) is provided in the lower portion of the floating bar (30), at least one hoist (50a ~ 50d) is provided with a chain (51a ~ 51d), the chain (51a ~ 51d) is a large In order to levitate the block unit MB into the air, it may be connected to the edge 53 of the large block unit MB. Although the case in which the chains 51a to 51d are provided in the hoists 50a to 50d shown in FIGS. 6a to 6d as an example has been described, the present invention is not necessarily limited thereto, and the chain ( It is also possible that a wire is provided instead of 51a to 51d). However, hereinafter, for convenience of description, a case in which the chains 51a to 51d are provided on the hoists 50a to 50d will be described as an example.

Specifically, the crane positions the floating bar 30 to be spaced apart from the upper part of the large block unit MB, and, for example, as shown in FIG. 6a, at least one hoist installed in the floating bar 30 (50a to 50d) In the case of four, the chains 51a to 51d provided in each of the four hoists 50a to 50d may be respectively connected to the four corner portions 53 provided in the large block unit MB.

At this time, the length of the chains 51a to 51d respectively connected to the four corner portions 53 provided in the large block unit MB may be approximately equal to L1.

In FIG. 6A , a case in which the chains 51a to 51d provided in at least one hoist 50a to 50d are connected to the four corners of the large block unit MB is illustrated as an example, but the present invention is not limited thereto , the chain provided in at least one hoist may be additionally connected to the center of both sides in the longitudinal direction of the large block unit MB as well as the four corners of the large block unit MB. As an example, it is also possible that the chain provided in at least one hoist is additionally connected to both sides of the large block unit (MB) intersecting the rotation axis.

In this way, in a state in which the chains 51a to 51d of the hoists 50a to 50d are connected to the large block unit MB, using a crane, the large block unit MB can be levitated in the air.

As shown in Figure 6a, in the state in which the large block unit (MB) is levitated in the air in the levitation step (S310), at least one hoist (50a ~ 50d) provided in the buoyancy bar 30 in the rotation step (S320) ) to control the length of the chain (51a ~ 51d) provided in each hoist (50a ~ 50d) can be adjusted.

Specifically, in the rotating step (S320), at least one hoist (50a ~ 50d) is the length of the chain (51b, 51c) connected to the edge of one side of the large block unit MB is reduced from L1 to L3, the large block The length of the chains 51a and 51d connected to the corner of the other side of the unit MB may be controlled to increase from L1 to L2.

As an example, chains 51b and 51c provided in two hoists 50b and 50c among the four hoists 50a to 50d are connected to one corner of the large block unit MB, and the remaining two hoists 50a, When the chains 51a and 51d provided in 50d) are connected to the other corner, in the rotating step S320, the length of the chains 51b and 51c connected to one side of the large block unit MB is reduced to L3. The hoists 50b and 50c may be controlled, and the remaining two hoists 50a and 50d may be controlled so that the length of the chains 51a and 51d connected to the other side of the large block unit MB is increased to L2.

Accordingly, the length of the chains 51b and 51c provided in the two hoists 50b and 50c in the rotation step S320 is decreased from L1 to L3, and the length of the chains 51b and 51c provided in the two hoists 50b and 50c is reduced from L1 to L3, and the length of the remaining two hoists 50a and 50d is provided. The length of the chains 51a and 51d may increase from L1 to L3.

In this way, by adjusting the length of the chains 51a to 51d of each hoist 50a to 50d, the large block unit MB rotates in a direction in which it stands in a suspended state in the air, as shown in FIG. 6b . The angle formed by the plane of the large block unit MB with the ground may be greater than or equal to a predetermined angle.

As an example, the angle θ formed by the plane of the large block unit MB with the ground may be at least 45° to 90°. More preferably, the angle θ formed by the plane of the large block unit MB with the ground may be at least between 60° and 90°.

When the angle (θ) formed by the plane of the large block unit (MB) with the ground is between 45° and 90°, by the weight of the plurality of exterior panels 100 for construction, it intersects with the longitudinal direction of the frame unit 110 Since the force applied in the lateral direction may be formed to be smaller than the maximum value, it may be maintained smaller than the allowable weight limit of the frame unit 110 .

As such, in the rotating step (S320), the other side of the large block unit MB may be seated on the ground in a state in which the large block unit MB is rotated by a predetermined angle or more.

Then, as shown in Figure 6c, at least one hoist (50a ~ 50d) is controlled so that the inclination angle (θ) is further increased in a state where the other side of the large block unit (MB) is seated on the ground, the large block unit ( MB) and the angle formed by the ground may be approximately 90°.

In this way, in a state where the angle θ between the large block unit MB and the ground is approximately 90°, as shown in FIG. 6d , the chains 51a to 51d connected to the other side of the large block unit MB are It can be removed from the large block unit (MB).

In this way, in a state where the angle θ between the large block unit MB and the ground is approximately 90°, the weight direction of the plurality of exterior panels 100 is formed in a direction parallel to the longitudinal direction of the frame unit 110, There is little possibility that the frame unit 110 is bent.

Then, in the fixing step (S400), as shown in FIGS. ) can be fixed to the wind beam 12 provided in. As such, when the large block unit MB is fixed to the floor plate 11 or the wind beam 12 of the building 10, the frame unit 110 coupled to the rear surface of the large block unit MB is a coupling member It can be fixed to the interlayer structure of the building 10 or the windbeam 12 by (14).

Accordingly, as shown in FIG. 1 , the outer wall of the building 10 can be constructed with a large block unit MB.

So far, according to an example of the present invention, a method has been described in which the large block unit MB is constructed as an outer wall of the building 10 .

Hereinafter, various structures in which the large block unit MB is fixed to the building 10 through the fixing step S400 will be described.

8 to 10 are roads for explaining various structures in which the large block unit MB is fixed to the building 10 according to an example of the present invention, and FIGS. 8 to 10 (a) are in the building 10 The fixed large block unit MB is viewed from the rear side, and FIGS. 8 to 10 ( b ) are views of the large block unit MB looking down from the front upper part.

In the construction structure of the large block unit MB according to the present invention, as shown in FIGS. 8 to 10 , the large block unit MB is directly connected to the first large block unit MB1 and the first large block unit MB. It may include a second large block unit (MB2) located adjacently, and in the fixing step (S400), the first side end and the second unit of the exterior panel 100 for construction included in the first large block unit (MB) The second side ends of the building exterior panel 100 included in the block unit MB may be installed to overlap each other.

As an example, a first example of a structure in which the large block unit MB is fixed to the building 10 is, as shown in FIGS. ) may be installed in the large block unit forming step (S200) so that the first and second frame units 110a, 110b, 110c fixed to the first and second side ends in the horizontal direction of the large block unit MB are located.

In the fixing step (S400), the first frame unit 110a coupled to the first side end of the first large block unit MB1 and the second frame unit coupled to the second side end of the second large block unit MB2 ( 110b) may be installed facing each other and spaced apart from each other, and in addition, the first side end of the first frame unit 110a and the third large block unit MB3 coupled to the second side end of the first large block unit MB1 The third frame unit 110c coupled to may be installed facing each other and spaced apart from each other.

Here, the first side end of the exterior building panel 100a included in the first large block unit MB1 protrudes more than the first frame unit 110a coupled to the first side end of the first large block unit MB1. , may overlap the second side end of the exterior panel 100 for construction included in the second large block unit MB2. In addition, a gasket protruding in the thickness direction of the large block unit MB may be provided between the first side end of the first large block unit MB and the second side end of the second large block unit MB overlapping each other have.

Accordingly, in the present invention, the first side end of the exterior building panel 100 included in the first large block unit MB is the second side end of the exterior building panel 100 included in the second large block unit MB, and By overlapping, the gap between the first large block unit MB and the second large block unit MB is sealed, and the thermal bridge blocking effect by the large block unit MB can be maximized.

However, with some changes from the structure shown in FIG. 8 , the first frame unit 110a is formed to be spaced apart from both side ends of the first large block unit MB1 in the large block unit forming step ( S200 ), and the second large block unit is formed. The second frame unit 110b may be formed to be spaced apart from both side ends of the block unit MB2.

In addition, in the fixing step ( S400 ), the first frame unit 110a coupled to the first side end of the first large block unit MB1 and the second frame coupled to the second side end of the second large block unit MB2 The units 110b are installed facing each other and spaced apart from each other, and between the first frame unit 110a and the second frame unit 110b, the exterior panel 100a for construction of the first large block unit MB1 and the second large block It is also possible that the adjacent ends of the building exterior panel 100b of the unit MB2 are formed to overlap each other in the horizontal direction.

As another example, as shown in FIGS. 9 and 10 , in the second example of the structure in which the large block unit MB is fixed to the building 10 , the first side end and the second side end of the first large block unit The frame unit 110 coupled to at least one side end of the first large block unit (MB) to be located more protruding than at least one side end of the first side end and the second side end of the exterior panel 100 for construction included in the , can be installed in the large block unit formation step (S200).

In addition, in the fixing step (S400), the frame unit 110 coupled to at least one of the first side end and the second side end of the first large block unit is included in the second large block unit building exterior panel 100 It can be installed so as to overlap the side end of the.

As an example, as shown in (a) and (b) of Figure 9, each of the first and second large block units (MB1, MB2) is only the first side end (E100a1, E100b) frame units (110a, 110b) However, each of the frame units 110a and 110b located at the first side ends E100a1 and E100b is a first side end ( It may be located more protruding than E100a1 and E100b).

In the state in which the first and second large block units MB1 and MB2 have the structure as shown in FIG. 9 , in the fixing step S400 , as shown in FIG. 9B , the first of the first large block units MB1 The frame unit 110a coupled to the side end E100a1 may be installed to overlap the second side end E100c of the exterior building panel 100c included in the second large block unit MB3.
